Topic: Failing TLSv1.2 handshake
I've got Wolf ver3.14 running on a WinCE6 device. It is running an SMTP client. I'm not having much success getting through the TLSv1.2 handshake. If I try to connect to my own PostFix server I have consistent success. If I try to connect to Gmail or Yahoomail I have a 98% failure rate. I suspect the server is closing the TCP session due to an improper handshake. I'm unable to prove this. The only feedback I get is the server closing the session [FIN, ACK].
I have attached a *.CAP of the traffic. There are a few TCP issues. (This is a high latency [many seconds], low bandwidth [modem] use case.) I'm thinking the latency is not an issue for the handshake as TCP will address these issues.
Is there anything that jumps out as a TLS issue? As in, why does the handshake die?
I can't tell if I am chasing a TLS, TCP, or firewall issue.
